I am trying to commission a brand new S5. It is assembled and connected per the instructions. When I tried to heat the machine up for a test print, the bed heated to between 70-73 C and then says:
I've tried several times, both with the glass on and with it off and I get the same results. I've checked the pins on the connector and the sockets on the P/S. I measured voltage at the connections on the heat bed and I get just over 11VDC when the bed is heating.
